Yet notwithstanding "Brick" is a twisted noir-genre story, the plot is constantly sprayed in cold surrealism, so now, my "Brick" Allegorical Interpretation:
"For me Laura's character (Nora Zehetner) would be the "Fatale



When did Brendan get disconnected from real world?

He's practically immune to Laura's manipulation for this motive, he suffers of a "schizo" process after being exposed to an evil femenine universe.
Kara and Dode are satellite characters in the story, on one hand Kara stands for Decadende (although minor compared with The Pin's or Laura's) and Dode stands for a minor Decadence (consequence of his drug consumption), but meanwhile Decadence makes Kara strong, makes Dode weak.
Emily (Emilie de Ravin) would stand for Purity (a purity symbol),

Jerr's bringing down by Brendan confirmed Emily about his cold head/ruthless "operative" and thereafter she chooses not to listening his reasoning, becoming more and more emotionally torn/disoriented. Her disorientation is used by Laura (whom had already known Jerr -this isn't mentioned in the film, but in the script) in a definitive destructive way that leads Emily to death.

Brendan doesn't admit the truth he was searching so anxiously/irrationally and, like "Memento"'s protagonist, chooses to live in denial, chooses to lie to himself after Laura's confession, and orders his Brain go to sleep, closing the Emily's episode -the only thing he loved- without accepting that dirty word, which despite of being literally "Motherfucker", it echoes clearly to "Motherkiller" (imo), in the sense the very Brendan's extreme isolation from reality leaded Emily to death and to his own defeated life after that."
I know it has been a looong theory, but I hope you like it. And I found an article about the femme-fatale figure, linked randomly to a matriarchate. Some excerpts from it:
"In a place, then, where there is no room for the solar hero, female figuration takes the initiative in the story, seizes the dark kingdom of film noir and broadens the blurred morality of the genre: seducers, frauds, killers with a kiss, they also block off any attempt at a linear plot and ruthlessly hurl the hero towards a desolate dead end."
